Design And Implementation Of Decision Supporting System For Integrated Management Of Land And Resources

Land and resources information system is a prerequisite for modernization andscientific management of land and resources, land and resources and the change of thecultivated land is concerned about the content. Along with the rapid economicdevelopment, a large number of rural cultivated land occupied by factories and otherbuildings, arable land area is changing, traditional hand-measured of arable landchanges already can’t meet the current demand for land and resources. Slope map bymaking software, import the corresponding argument can easy access rate and improvethe accuracy of data in the gradient in the gradient. Therefore, with a gradient of thesefunctions the software development is imminent.This article describes in detail the gradient map production system research anddesign process. Overall demand for combination of slope mapping software, gradientcalculated for districts, trivial patch to deal with comprehensive statistical analysisresults in the gradient and in-depth studies of demand for these three areas, considereddesign platforms and software development technologies, design gradient mapproduction system.The gradient mapping system uses the most common map making softwareplatform Arcgis9.2, with good versatility and compatibility. Calculation of slope andrating, framing, slope County data processing, to level slope data that features four large,through systems of software testing and test result analysis. Slope can be derivedsoftware are well in place of artificial slope of the trivial and complicated calculations,greatly improves data accuracy and precision in the gradient. Slope map software tobetter meet a land and resource management on slope measurement computing-relatedrequirements, for their work is much easier in the future.
